Patent GB-740681-A (GB)
Title: Improvements in or relating to level-indicating or stable reference apparatus
IPC: G01C19/44
Filed: 1948-04-02
Abstract: 740,681. Automatic antenna control systems. SPERRY CORPORATION. April 2, 1948 [July 9, 1947], No. 9347/48. Class 38 (4). [Also in Groups XL-(b) and XL (c)] In an aircraft, reference co-ordinates are produced by scanning the horizon either in a circular fashion with a radar antenna or vertically by a photo-electric device and the error signals so derived are applied to maintain a gyro-vertical erect. As shown, Fig. 2, the antenna 14 is rotated about axis 11 so as to scan a circle in azimuth and the scanning axis 11 is maintained automatically in alignment with the gyro vertical 35 by means of the torque motors 25, 26 energized from the Selsyns 52, 50. Tilting of the gyro, due, e.g., to the earth's rotation, causes tilt of axis 11 and this causes an unbalance signal, detected at antenna 14, to be applied through receiver 43 and transformer 63 to the torque motors 51, 53 and the gyroscope and the axis 11 are both maintained vertical. The manually adjustable Selsyns 66, 67 may be connected to the ailerons and elevators respectively and the craft stabilizer at predetermined bank and climb (or glide) angles. Correction for the earth's rotation is effected by the gyro compass 72 and the transformer 64. In an alternative form, not shown, the antenna may be mounted directly on the gyroscope. In Fig. 4, the horizon is scanned in two perpendicular directions through the lenses 107 mounted in the housing 100 which carries the gyroscope 105 and which is supported by the gimbal 101 for movement with respect to the craft about two perpendicular axes. Scanning is effected by the oscillating mirror 109 which reflects the radiation from the horizon on to the photo-electric cell 108. The signal developed by the discontinuity at the horizon is differentiated and its phase difference with respect to the mirror oscillations is measured to produce an error signal indicating the deviation of gyroscope axis from the vertical. The error signal is applied to the torque motors, 114, to precess the gyroscope. In a further embodiment, not shown, a photoelectric system is mounted on a gyro-vertical and adapted to view the horizon in a single direction only and the error signal is developed by tilting of the gyroscope and photo-electric system without mechanical scanning. Specification 596,572, [Group XXXVII], is referred to. The Specification as open to inspection under Sect. 91 comprises also an aircraft pitch controlling arrangement in which the horizon is viewed either by a radar or photo-electric means secured regidly to the aircraft. This subjectmatter does not appear in the Specification as accepted.

Ventilating shafts.-A duct for use in drying chambers is formed to give substantially an even flow of gases from it at each unit of its length and is of the form uniformly tapered lengthwise and provided with a longitudinal slot 8 for sideways flow of fluid. The slot is covered bv an apron 4 separated from the side 9 of the duct and provided with a wire-beaded top edge 7.

The duct may be rolled from a sector-shaped blank to form a conical duct with covering apron 13 over aperture 11, Fig. 5. For a suction duct, the sideways entrance slots would be of the shape formed by an apron 16, as shown in Fig. 9.

Abstract: 579,529. Packing granular material. QUAKER OATS Co. May 17, 1944, No. 9474. Convention date, June 18, 1943. [Class 94 (i)] In an apparatus in which loose compressible materials such as rolled oats, meal &c. are packed into containers by means of a rotating auger or propeller 22 arranged within a material feed tube 16 extending into the container 5 which is supported by a table 7 gradually lowered as the packing continues, stationary buffers such as 29 are arranged immediately above the auger to reduce rotation or turbulence of the material in this region, thus allowing of greater compression of the material into the container. The baffles may be fixed as shown to a stationary tube surrounding the auger shaft 20 or may be secured to the inner surface of the feed tube 6. The table 7 is positively lowered by screw and nut gear at a fixed predetermined speed to control the degree of compression, a quick return drive being provided for engaging an empty container with the tube 6.

Tubing, e.g. plastics tubing from an extruder, is cut into lengths by apparatus comprising a rotatable carriage which supports a cutting device and through which the tubing continuously passes. A detecting element controls a servo-mechanism actuating the cutting element of the cutting device. The cutting device comprises a carrier 3 which is rotated by an electric motor and which supports a knife 92 movable radially towards the tubing by a dog leg cam 45 carried by a cam ring 48 which is concentric with the carrier and which is movable by a pivoted cross-head actuated by a fluid motor 60 the supply to which is controlled by a servovalve actuated by the detecting element comprising a rocking lever 73, carried by an adjustable bracket. The carrier moves with the tubing by virtue of the engagement between the cutting blade and the tubing but a pneumatically operated servo-controlled clamping device may be provided for this purpose.

Abstract: 1459448 Measuring fluid-flow NATIONAL RESEARCH DEVELOPMENT CORP 20 Feb 1974 [27 Feb 1973] 9536/73 Heading G1N Apparatus for measuring the flow velocity of a fluid includes a wire 12 energized by current pulses from generator 10 timed by control 11, the resulting temperature increase in the fluid being sensed by a thermistor wire 13 or 14, respectively  upstream and downstream of the heater wire for a given flow direction, in a bridge, the output from which is fed to the differential amplifier 20 through two parallel paths. One of these paths includes a switch 23 controlled by control 11 so that the amplifier inputs are nulled when the switch is closed, whereby spurious signals induced in wire 13 or 14 by the current pulse in the heater wire are suppressed, the resulting signal being passed to a further circuit which determines the time interval between a current pulse in the heater wire and a resulting temperature change of a thermistor wire, which interval is an indication of fluid velocity. The further circuit includes two comparators 27, 28 providing respectively positive output signals for flow in one direction or the other to set one or other of bi-stables 32, 33 causing display unit 41 to indicate flow direction. Setting of a bi-stable 32 or 33 triggers OR gate 37 and OR gate 38 to set bi-stable 42 to act on gate 43 to stop pulses from clock generator 35 passing into counter 44, which gate is opened by the control 11 when the heater wire is pulsed, by a signal from the control to the bi-stables 32, 33. Thus the count indicates flow velocity.

Abstract: 692,202. Gas turbine plant. DOWTY EQUIPMENT, Ltd. April 17, 1951 [April 19, 1950], No. 9655/50. Class 110(iii) [Also in Group XXIX] In a liquid fuel regulating system for aircraft gas turbine engines having burners of the spill type, the fuel supply means are regulated by a servomotor under the control of a vent valve the closure member 21 of which is movable in response to the pressure difference between the high and low pressure sides of the burners. In Fig. 1. the burners 13 are supplied from an engine driven circulating pump 11 through a pipe 12 and fuel returns to the pump inlet via a pipe 14. The pressures in the pipes 12, 14 are conveyed through pipes 28, 29 to the servomotor control means 20 which are also connected by a pipe 23 to a servomotor regulating an engine driven fuel supply pump 15 and by a pipe 24 to the inlet of the pump 15 or to a fuel tank 17. The servomotor may control a by-pass valve in the case of a fixed stroke pump or the pump stroke-varying element in the case of a variable-stroke pump. In one form, the servomotor control means 20 includes a vent valve 21. Fig. 4. controlling the leakage of fuel from the pipe 23 to the pipe 24. The valve head 21 is formed on a rod 25 carrying a piston 26 (or a diaphragm) exposed through the pipes 28, 29 to the pressure difference across the spill-burners. This pressure difference has been found to vary substantially as a function of engine speed irrespective of changes in altitude so that the apparatus described functions as an all-speed governor, the datum speed being adjusted by varying the loading of a spring 20 by a cam 31 actuated by the pilot's lever 32. In Fig. 5, the piston 26 is replaced by the opposed bellows 36, 37 connected to pipes 28, 29 respectively and acting on a lever 34 bearing a half ball valve 33 controlling the vent 22. The lever 34 is also influenced by a bellows 38 the hydraulic loading in which is varied by means of a constant speed pump 39 having a by-pass valve 40 adjusted by the pilot's lever 32.
